Abstract
A self-cleaning woven wire screening or screen for classifying material. The screening includes a plurality interwoven warp and weft wires forming a plurality of openings in a screen section through which materials to be classified can pass through. The weft wires are preferably configured so that the high points or raised knuckles of the weft wires have a larger diameter, cross-sectional height or thickness than previously possible. Preferably, one or more of weft wires have a configuration that prolongs operational life of the screen or screening and obviates the need for protective encasement blocks (e.g., polyurethane encasement blocks) encasing the weft wires.
